3D modeling systems require more efficient and effective design methods, building on prior Free‑Form Deformation techniques. The study introduces a highly interactive and intuitive deformation technique that allows designers to create arbitrarily shaped bumps and bend surfaces along arbitrary curves. The technique extends Free‑Form Deformation by using a user‑defined deformation tool that mimics sculpting and moulding, enabling interactive manipulation of geometry.
Current research efforts focus on providing more efficient and effective design methods for 3D modeling systems. In this paper a new deformation technique is presented. Among other things, arbitrarily shaped bumps can be designed and surfaces can be bent along arbitrarily shaped curves.The purpose of this research is to define a highly interactive and intuitive modeling technique for designers and stylists. A natural way of thinking is to mimic traditional trades, such as sculpturing and moulding.Furthermore, with this deformation technique, the modeling tool paradigm is introduced. The object is deformed with a user-defined deformation tool.This method is an extension of the Free-Form Deformation (FFD) technique proposed by Sederberg and Parry [17].
